Jason Alexander, best remembered for starring in a little-known sitcom called Seinfeld, has been cast as Cliff Beamis, the writer/creator of The Grinder‘s titular show-within-a-show in which Lowe’s character starred for eight seasons.

The news was broken late Tuesday night by Lowe on Twitter, following the show’s panel at PaleyFest in Los Angeles:

TV legend Jason Alexander will play the writer/creator of "The Grinder," the egomaniac and ersatz tough-guy Cliff Beamis. Welcome aboard!

Since Seinfeld wrapped in 1998, Alexander has starred in a number of short-lived series, including ABC’s Bob Patterson and CBS’ Listen Up! He also appeared in several episodes of HBO’s Curb Your Enthusiasm, playing himself.

If you weren’t already planning on tuning in to The Grinder, premiering Sept. 29 at 8:30/7:30c, is Alexander’s casting enough to change your mind? Drop a comment with your thoughts on this addition below.
